FA-08 or V-760

[LesliesTube]

I'm considering to sell/trade my Jupiter-50, it's a lovely board but not for what I need and use.
There's a guy selling a VR-760 in 4000NIS (~1000USD), it tempts badly and the GAS is "leaking".
Now comes the real dilemma.
I am really interested at having the SRX-07 card, that is also available in digital form (not with all waveforms) to the FA keyboards. For free.
The VR-760 includes a fully modelled B3 simulation, a la VK8. Whilst the FAs have a rather useful modelled organ, but it lacks Chorus\Vibrato. I tend to use some sampled organs too, some are really meaty and there are certain occasions where I can't miss the "fullness" of the sound.
Considering the sampled organs too, these expansions include more useful synths, string machines etc, and all around they are highly useful for my needs.
The last and most important question, can either the VR-760 and the FA access to the basic waveforms in these expansions? If there are some sounds I'd like to tweak, I'd rather create them from scratch.
